2011 AUG 3 - (VerticalNews.com) -- "The Japan Meteorological Agency (JMA) isrnable to process data for its earthquake early warning (EEW) procedure very quickly byrnemploying a seismic intensity expectation method that uses simplified strong motionrncharacteristics. To represent one of these characteristics, the site amplification factor at thernseismic intensity station, JMA uses ARV (amplitude ratio of peak ground velocity at the groundrnsurface relative to the engineering bedrock of average S-wave velocity 700 m/s) based onrntopographic data," scientists writing in the journal Earth Planets and Space report.
